Primary Outcome Measures:
  • Maximum Tolerated Dose acceptable for participants [ Time Frame: 4 weeks ]
    The Maximum Tolerated Dose will be determined by a Data Safety Monitoring Board

Secondary Outcome Measures:
  • Efficacy [ Time Frame: After 8 weeks and then every 12 weeks ]
    Efficacy will include overall response rate and duration of response

Other Outcome Measures:
  • Pharmacokinetic profile including Peak Plasma Concentration (Cmax) [ Time Frame: Up to 6 months ]

Enrollment: 10
Study Start Date: December 2012
Study Completion Date: October 2014
Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ublituximab + Lenalidomide

4 cohorts, with 3 - 6 patients per cohort, as follows:

  • Cohort 1: Ublituximab 450 mg + Lenalidomide 10 mg
  • Cohort 2: Ublituximab 450 mg + Lenalidomide 15 mg
  • Cohort 3: Ublituximab 600 mg + Lenalidomide 10 mg (escalation to 15 mg permitted after cycle 1)
  • Cohort 4: Ublituximab 900 mg + Lenalidomide 10 mg (escalation to 15 mg permitted after cycle 1)

Ublituximab is an IV infusion on days 1, 8, and 15 of cycles 1 & 2 followed by a planned maintenance with a single infusion on day 1 of cycles 3 thru 6.

Lenalidomide is taken orally on days 9 - 28 of cycle 1 followed by daily administration on Days 1 - 28 for cycles 2 thru 6. Non-hodgkins lymphoma patients may have up to a 7 day rest period (Days 21-28) in any cycle.

Drug: Ublituximab
Ublituximab is a novel monoclonal antibody targeting CD20
Other Name: TG-1101
Drug: Lenalidomide
Lenalidomide has both immunomodulatory and anti-angiogenic properties which could confer antitumor and antimetastatic effects
Other Name: Revlimid
